righttirefire Posted February 21, 2015 Share Posted February 21, 2015 Good Morning All, I know this seems silly, but personally I'm a visual learner and anything I can measure and document is enjoyable for me. As you can see I scaled the corner of my tank. They're labeled as 4 cups, 8 cups, 12 cups, 1 gallon, and 2 gallon. It encourages water top offs and gives me an easy to see 10% water change level, in hopes of maintaining consistency. Consistency is key. Here's the MATH! 7.48 gallons of a liquid is 1 cubic foot volume. With this ratio, 1 gallon equals 231 cubic inches. My tank, 20h, has an outside dimension of 24" x 12-1/4", glass thickness 3/16". Making the inside dimensions of my tank 23-5/8" x 11-7/8", giving me and area of 280.547 square inches. The given 231 cubic inches divided by 280.547 square inches of my tank equals 0.823" (about 13/16") That's the base of my scale. 13/16" down from my desired water level is the 1 gallon mark. 1-5/8" down us my 2 gallon mark which is also 10% water change mark. (My 20h with 15# sand and 24# LR actual water volume is about 17 gallons) above the 1 gallon gallon mark is a half gallon, 8cups and the quarter gallon marks, 4 cups and 12 cups. As you can see my tank is about 1/2 gallon or 8 cups lower than my desired water level. I did some drip acclimations and I'm about to perform a water change. That's why my tank is low right now Link to comment
